[0002] Glass fiber is a high-performance inorganic non-metallic material with many varieties. Its advantages include good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength. Its disadvantages include high brittleness and poor wear resistance. Glass fiber is commonly used as a reinforcing material in composite materials and has wide applications in industry.

[0003] In current technology, most glass fiber winding processes use single-axis or dual-axis rotary winding. However, current winding equipment suffers from the following two problems, resulting in low production efficiency: 1. It is difficult to avoid glass fiber breakage due to excessive tension or loosening or knotting due to insufficient tension during the winding process. Broken fibers need to be spliced, and loosening or knotting requires rewinding, affecting winding efficiency and effectiveness; 2. The winding drum used for winding glass fiber is inconvenient to replace, requiring machine downtime for replacement, which further reduces production efficiency.

[0004] Therefore, in order to improve the winding efficiency of glass fiber, a new type of glass fiber winding device is needed. Summary of the Invention

Detailed Implementation

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Example

[0027] Reference Figure 1-6As shown, this embodiment provides a glass fiber winding device to prevent fiber breakage, including a support plate 1. The support plate 1 has a turntable 2, an inlet roller 3, and a fabric roller 4 arranged parallel to each other. The turntable 2 is rotatably connected to the support plate 1 and to a first rotary drive assembly 5. Two symmetrically arranged winding rollers 6 are rotatably connected to one end face of the turntable 2. The first rotary drive assembly 5 can drive the turntable 2 to rotate, thereby realizing the position exchange of the two winding rollers 6 and achieving rapid roller changing. The winding rollers 6 are connected to a second rotary drive assembly 7, which provides rotational power to the winding rollers 6, thereby achieving the winding of the glass fiber. The inlet roller 3 and the fabric roller 4 are located on the same side of the turntable 2, and the height of the inlet roller 3 from the ground is higher than that of the fabric roller 4. After being introduced from the inlet roller 3, the glass fiber passes around the fabric roller 4 and winds onto the winding roller 6. One end of the fabric roller 4 is connected to a rotary telescopic drive assembly 8, which drives the fabric roller 4 to rotate while reciprocating along its length. The fabric roller 4 is equipped with at least one tension adjusting element, and multiple tension adjusting elements are provided to synchronously wind multiple glass fibers. In this embodiment, two tension adjusting elements are provided. The tension adjusting element includes several bent rods 9 evenly distributed along the circumferential direction of the fabric roller 4. In this embodiment, each tension adjusting element includes four bent rods 9. When the glass fiber passes through the tension adjusting element, it passes through one of the bent rods 9 and is then led out from the bottom of the fabric roller 4 to the take-up roller 6. Both ends of the bent rod 9 are fixedly connected to the fabric roller 4. The distance from the bent rod 9 to the fabric roller 4 gradually increases and then gradually decreases from one end of the bent rod 9 to the other end. The bent rod 9 is used to drive the glass fiber to move with the reciprocating movement of the fabric roller 4, thereby enabling the glass fiber to be evenly wound on the take-up roller 6. In addition, the shape design of the bent rod 9 can appropriately compensate for the tension changes generated during the reciprocating movement of the glass fiber driven by the bent rod 9. The bent rod 9 is a bent rod with a circular axial cross section to avoid wear on the uneven surface of the bent rod 9 when the glass fiber comes into contact with the bent rod 9.

[0028] In use, the take-up drum is coaxially fixed to one of the take-up rollers 6. Then, the ends of the filamentous glass fibers, corresponding to the number of tension adjusters, are introduced from the inlet roller 3, pass through the corresponding tension adjusters, and exit from the bottom of the fabric roller 4. The glass fibers are then wound onto the take-up drum. The second rotary drive assembly 7 is activated to drive the take-up roller 6, causing the take-up drum to rotate synchronously, thus achieving the winding of the glass fibers. The rotary telescopic drive assembly 8 is activated, causing the fabric roller 4 to rotate while reciprocating along its length, thereby enabling the tension adjusters on the fabric roller 4 to function and achieve winding of the glass fibers onto the take-up drum. The winding process is uniform, and the shape design of the bent rod 9 in the tension adjustment component compensates for the changes in tension on the glass fiber caused by the movement of the glass fiber driven by the cloth roller 4 during the winding process, preventing fiber breakage. During the winding operation of the winding roller 6 with the winding drum, another winding drum can be coaxially fixed on another winding roller 6. When the winding drum finishes winding, the glass fiber is broken, and the first rotary drive component 5 is activated to drive the turntable 2 to rotate, thereby exchanging the positions of the two winding drums. The above actions are repeated to continue the winding operation, thus realizing the rapid replacement of the winding drum and improving work efficiency.

[0029] In a further preferred embodiment, the first rotary drive assembly 5 includes a roller-changing auxiliary gear 51, a roller-changing main gear 52, a roller-changing drive motor 53, and a telescopic limiting rod 54. The roller-changing auxiliary gear 51 is coaxially fixedly connected to the curved sidewall of the turntable 2, and the roller-changing auxiliary gear 51 and the take-up roller 6 are located on opposite sides of the support plate 1. The roller-changing auxiliary gear 51 is meshed with the roller-changing main gear 52, and the roller-changing main gear 52 is fixedly connected to the output shaft of the roller-changing drive motor 53. In this embodiment, the roller-changing drive motor 53 is fixed on the support plate 1. One end of the telescopic limiting rod 54 is connected to the translation drive device 55, and the other end of the telescopic limiting rod 54 is adapted to the gap structure between two adjacent teeth on the roller-changing auxiliary gear 51. In this embodiment, the translation drive device 55 is fixed on the support plate 1. The translation drive device 55 can be a hydraulic cylinder. The telescopic rod of the hydraulic cylinder is connected to the telescopic limit rod 54. The hydraulic cylinder is connected to an oil tank containing oil through a hydraulic pump. When the hydraulic pump supplies oil to the hydraulic cylinder, the telescopic rod on the hydraulic cylinder extends and drives the telescopic limit rod 54 to extend into the space between two adjacent teeth on the roller changing gear 51. When the hydraulic pump draws the oil out of the hydraulic cylinder, the telescopic rod on the hydraulic cylinder retracts and drives the telescopic limit rod 54 to move out from the space between two adjacent teeth on the roller changing gear 51.

[0030] In use, when it is necessary to exchange the positions of the two take-up drums, the translation drive device 55 starts to drive the telescopic limit rod 54 to move out from between two adjacent teeth on the roller changing gear 51. Then, the roller changing drive motor 53 starts and transmits the rotational power to the turntable 2 in sequence through the roller changing main gear 52 and the roller changing gear 51, so that the turntable 2 rotates 180 degrees, thereby completing the position exchange of the two take-up drums 6. Since the take-up drums are coaxially fixed on the take-up drums 6, the position exchange of the two take-up drums can be realized. After the two take-up drums complete the position exchange, the translation drive device 55 starts to drive the telescopic limit rod 54 to extend into between two adjacent teeth on the roller changing gear 51 to ensure the stability of the position of the turntable 2.

[0031] In a further preferred embodiment, the second rotary drive assembly 7 includes a winding auxiliary gear 71, a winding main gear 72, and a winding drive motor 73. There are two winding auxiliary gears 71, each coaxially fixedly connected to the curved sidewalls of the two winding rollers 6, with one of the winding auxiliary gears 71 meshing with the winding main gear 72. The winding main gear 72 is fixedly connected to the output shaft of the winding drive motor 73; in this embodiment, the winding drive motor 73 is fixed to the support plate 1.

[0032] In use, the winding drive motor 73 starts and transmits rotational power to the winding roller 6 in sequence through the winding main gear 72 and the winding secondary gear 71, thereby realizing the rotation of the winding roller 6 and the winding drum fixed thereon to perform the winding action of glass fiber.

[0033] In a further preferred embodiment, the rotary telescopic drive assembly 8 includes a telescopic drive device 81, a rotary drive motor 82, a driving gear 83, and a driven gear 84. The telescopic drive device 81 is horizontally fixed to the support plate 1. The telescopic end of the telescopic drive device 81 passes through the support plate 1 and is fixedly connected to the fabric roller 4. The telescopic drive device 81 can be a hydraulic cylinder. The driven gear 84 is fixedly connected to the telescopic drive device 81. In this embodiment, the driven gear 84 is fixedly connected to the cylinder of the telescopic drive device 81. The axis of the driven gear 84, the telescopic drive device 81, the telescopic part, and the fabric roller 4 are located on the same straight line, ensuring that after the rotational power from the rotary drive motor 82 is transmitted to the telescopic drive device 81, the fabric roller 4 can rotate stably around its own axis. The driven gear 84 meshes with the driving gear 83, which is fixedly connected to the output shaft of the rotary drive assembly. In this embodiment, the rotary drive motor 82 is fixed to the support plate 1.

[0034] In use, the rotary drive motor 82 transmits the rotational power to the telescopic drive device 81 through the drive roller gear and the driven gear 84 in sequence, so that the telescopic drive device 81, the telescopic part and the fabric roller 4 rotate synchronously. At the same time, the telescopic drive device 81 drives the fabric roller 4 to reciprocate along the length of the fabric roller 4, so that the fabric roller 4 can use the tension adjustment element to evenly lay the glass fiber.

[0035] In a further preferred embodiment, a tension adjusting component 10 is provided on the same side of the inlet roller 3 and the fabric roller 4. The tension adjusting component 10 includes a guide rail 101 fixed on the support plate 1, and a spring 102 and a slider 103 are provided inside the guide rail 101. The length direction of the spring 102 is parallel to the length direction of the guide rail 101. One end of the spring 102 is fixedly connected to one end of the guide rail 101, and the other end of the spring 102 is fixedly connected to the end face of the slider 103 away from the inlet roller 3 and the fabric roller 4. The slider 103 is slidably disposed inside the guide rail 101, and a tension roller 104 arranged parallel to the inlet roller 3 is fixedly connected to the slider 103. A threading ring 105 corresponding to the tension adjusting component is fixedly connected to the tension roller 104.

[0036] In use, a roller can be connected to the contact surface between the slider 103 and the guide rail 101. The roller reduces the frictional resistance between the slider 103 and the guide rail 101, thereby making the tension adjustment component 10 more sensitive. Glass fibers are introduced from the inlet roller 3 into the threading ring 105 and then out of the threading ring 105. Subsequently, the glass fibers are threaded into the hole between one of the bent rods 9 and the cloth roller 4 and led out from below the cloth roller 4. Finally, the glass fibers are wound onto the take-up drum on the take-up roller 6. When the tension on the glass fibers increases, the glass fibers exert a force on the threading ring 105, causing the threading ring 105 to move along the guide rail 101 towards the end closer to the inlet roller 3 and the cloth roller 4, thereby reducing the tension on the glass fibers. When the tension on the glass fibers decreases, the slider 103, under the action of the spring 102, moves along the guide rail 101 away from the inlet roller 3 and the cloth roller 4, thereby increasing the tension on the glass fibers. Through the cooperation of the slider 103 and the spring 102, the tension on the glass fibers can be dynamically adjusted, further preventing the glass fibers from breaking during the winding process.

[0037] In a further optimized design, an elastic metal rod 11 is fixedly connected to the tension roller 104. One end of the elastic metal rod 11 is fixedly connected to the tension roller 104, and the other end is fixedly connected to the threading ring 105. The height of the elastic metal rod 11 from the ground gradually increases and then gradually decreases from the end furthest from the threading ring 105 to the end closest to the threading ring 105. The elastic metal rod 11 can deform when the tension on the glass fiber changes, and combined with the positional changes of the slider 103 and the threading ring 105, it achieves the adjustment of the glass fiber tension, increasing the sensitivity of the tension adjustment component 10.

[0038] A further preferred option is that the introduction roller 3 is rotatably connected to the support plate 1, specifically, the introduction roller 3 can be connected to the support plate 1 through a bearing.

[0039] In use, the rotary connection method allows the guide roller 3 to rotate when the friction between the glass fiber and the guide roller 3 is high, thereby reducing the wear between the glass fiber and the guide roller 3.

[0040] In a further optimized design, the curved sidewall of the take-up roller 6 is provided with evenly distributed through holes, and one end of the take-up roller 6 is connected to an air pump via an air pipe 12. An air bladder is provided inside the take-up roller 6, and the air bladder is connected to the air pipe 12. Several protrusions 13 are fixedly connected to the outer wall of the air bladder, and the protrusions 13 are slidably connected in the through holes, with the length of the protrusions 13 being greater than the length of the through holes.

[0041] In use, after placing the take-up drum onto the take-up roller 6, the air pump is activated to inflate the air bladder. Once inflated, the protrusion 13 moves outward along the through hole and abuts against the inner wall of the take-up drum, thus securing it to the take-up roller 6. To remove the take-up drum, simply use the air pump to extract the air from the air bladder. The air bladder deflates, and the protrusion 13 retracts and separates from the take-up drum, allowing it to be removed from the take-up roller 6. The combined use of the air bladder, through hole, and protrusion 13 facilitates the installation and removal of the take-up drum, making it more convenient to use.

[0042] In a further optimized design, a protective cover 14 is fixedly connected to one side of the support plate 1. The turntable 2, the guide roller 3, the fabric roller 4, and the tension adjustment assembly 10 are all located inside the protective cover 14. The protective cover 14 can prevent interference with the glass fiber during the winding process and can also, to a certain extent, prevent the dust and debris generated during the winding process from spreading into the air. The protective cover 14 is provided with a feed inlet, which is positioned above the guide roller 3, facilitating the guidance of the glass fiber to the guide roller 3. A maintenance door 15 is rotatably connected to the side of the protective cover 14 facing the support plate 1. The maintenance door 15 and the protective cover 14 can be magnetically sealed together. The maintenance door 15 facilitates the maintenance of the components inside the protective cover 14 and also facilitates the installation and removal of the winding drum from the winding roller 6.

[0043] When in use, open the maintenance door 15, install the winding drum on the winding roller 6, introduce the glass fiber into the feed roller 3 from the feed port, and then wind the end of the glass fiber onto the winding drum in the normal threading sequence. Then close the maintenance door 15 to carry out normal glass fiber winding work.

[0044] Therefore, the glass fiber winding device of the present invention, which adopts the above-mentioned structure, can adjust the tension of the glass fiber during the winding process, facilitate the replacement of the winding drum without stopping the machine, and thus improve the winding efficiency and winding effect.

[0046] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention.
